element1 ele开发者_StackOverflow社区ment2 element3       DELETE
element1 element2 element3       DELETE
element1 element2 element3       DELETE

Once all these are filled the user will click save and it will save in the db

Assuming that you want to do this in a custom table, then I would use ChronoForms and ChronoConnectivity. This will allow you to create a custom form with a custom database table with the ability to add/edit/delete table rows.
